Analysis of the Asphalt Mixes' Properties with Digital Image Processing Technique

The digital image processing technique was applied to analyze and evaluate the internal structure properties of asphalt mixes. The properties of different asphalt mixes specimens made with Marshall compaction, vibration compaction, gyratory compaction, and roller compaction methods were evaluated and compared with real asphalt pavement. It is found that the internal structure properties with different compaction method have great differences. The results indicate that the digital image processing technique is an effective way in evaluating the internal structure properties of asphalt mixes. The feasibility and importance of the digital image processing technique to enhance the asphalt mix design and improve the practical techniques are pointed out. Predictions are made on the development of this technique.
